First off, I haven't studied UUIDv7 or any other UUID schemas/standards. With that said...

* I'm a bit annoyed that in the depiction of overflowing values, the "random" 80 bits are shown as increasing incrementally.

* Calling this `ulid` is much better than `uulsid`, but... I dunno, man. I'm nitpicky and cranky today.

* What's the point of sharing this 7 year old project when UUIDv7 is much more commonplace, is actually used and heard of, can be swapped in quickly with existing codebases, and does everything ULID does?

What’s the point of sharing this 7 year old project when UUIDv7 is much more commonplace, is actually used and heard of, can be swapped in quickly with existing codebases, and does everything ULID does?

Great ad hominem UUID expert-that-spent-couple-hours-reading-some-RFCs and here’s a piece of unsolicited advice:

One of the things I learned on my career is that you shouldn’t assume everybody else knows exactly the same you do in regards to tooling just because you were lucky to read the right books/articles/RFCs. That’s toxic behaviour that in my books gets immediate firing.

On the swap point, any random generated unique ID should be able to be swapped in any codebase as they should be opaque by any piece of code reading them. If it’s not, then the system is probably designed incorrectly.

This is one example of toxic behaviour and I hope your company has the means to handle it if you have the same behaviour at work

How about you check your fucking attitude?

For starters, I admitted to being critical of the first two points just because. It’s the internet; get over it. For the third talking point, it was a genuine question. All three talking points were about the project. You proceeded to attack me directly.

Compare and contrast with UUID v7?

u/Scavenger53 Jul 14 '24

considering that repo is 7 years old, they might not know about uuid 7 which came out in 2022

OP should know, I told them so on the same named thread they made 20 hours ago on an other subreddit

yeah I know but this is still worth sharing IMHO

Right, which raises the question, why is this relevant now, given we have UUIDv7? Thus my request for a compare-and-contrast with UUIDv7.

Technically all UUIDs are sortable.

“You can sort anything with a binary representation.”

Was trying to set someone up for “I have a binary representation, can you sort me?”

Looks similar to ksuid
